<h2 id="第一代布局"><a href="#第一代布局" class="headerlink" title="第一代布局"></a>第一代布局</h2><h3 id="网络拓扑图"><a href="#网络拓扑图" class="headerlink" title="网络拓扑图"></a>网络拓扑图</h3><p><img src="https://image.dqv5.com/public/2021/12/26/1640526195382.png"></p>
<h3 id="存在的问题"><a href="#存在的问题" class="headerlink" title="存在的问题"></a>存在的问题</h3><ul>
<li>墙内只有一根网线，由它分出来两根线，一根接电视IPTV，另一根接无线路由器，导致客厅路由器端的网速最高只有百兆，其它房间的网速更是慢的可怜</li>
</ul>
<h2 id="第二代布局"><a href="#第二代布局" class="headerlink" title="第二代布局"></a>第二代布局</h2><h3 id="网络拓扑图-1"><a href="#网络拓扑图-1" class="headerlink" title="网络拓扑图"></a>网络拓扑图</h3><p><img src="https://image.dqv5.com/public/2021/12/26/1640526240374.png"></p>
<h3 id="说明"><a href="#说明" class="headerlink" title="说明"></a>说明</h3><ul>
<li>比上一代布局好的地方是，客厅的路由器可以跑满带宽了（500兆），房间二的网速也很不错（200多兆），其它房间网速都尚可。</li>
<li>仍存在的不足是，房间一的电脑和树莓派不能跑满带宽，并且二者之间传输数据有点麻烦。如果走无线，速度会很慢；如果给二者之间接一条网线，虽然可以解决问题，但是总觉得不够优雅。</li>
</ul>
<h2 id="我的计划"><a href="#我的计划" class="headerlink" title="我的计划"></a>我的计划</h2><h3 id="网络拓扑图-2"><a href="#网络拓扑图-2" class="headerlink" title="网络拓扑图"></a>网络拓扑图</h3><p><img src="https://image.dqv5.com/public/2021/12/26/1640526262919.png"></p>
<h3 id="说明-1"><a href="#说明-1" class="headerlink" title="说明"></a>说明</h3><ul>
<li>光猫还是移到房间一，并加入一台带AC管理的POE供电的一体化路由器（5网口就够），通过墙壁中的管道分别接到客厅和房间二，（房间三没有找到管道出口，不然也得接到房间三去）。</li>
<li>在房间二墙上安装带有AP功能的POE供电的网口面板，这样就不用一直插个无线路由器了，并且网速还能刚刚的。</li>
<li>树莓派和电脑也可通过网线连到一体化路由器上，解决了互相传输数据慢的问题。</li>
<li>心中想的计划比较完美，于是开始买买买了，20米的6类网线、网线钳、水晶头、一体化路由器、AP面板……</li>
</ul>
<h2 id="实施中遇到的难题"><a href="#实施中遇到的难题" class="headerlink" title="实施中遇到的难题"></a>实施中遇到的难题</h2><h3 id="管道中的线缆断了"><a href="#管道中的线缆断了" class="headerlink" title="管道中的线缆断了"></a>管道中的线缆断了</h3><p>首先要做的，就是把墙内的光纤换成两根网线。因为之前没自己动手操作过，缺乏实战经验，我直接用胶带将光纤与两根网线缠上，就开始拽了。结果管内阻力比较大，胶带粘的不牢固，线就脱落了。当时就告诉自己，线断了也有办法的。于是从淘宝上买了穿线器，心想，穿线器到了就可以继续了。</p>
<p><img src="https://image.dqv5.com/public/2021/12/26/1640530454455.jpeg"></p>
<h3 id="墙内的管道并不好走"><a href="#墙内的管道并不好走" class="headerlink" title="墙内的管道并不好走"></a>墙内的管道并不好走</h3><p>穿线器到了，开始从一个口往里捅。刚开始还很顺畅，一直往里走了好长的距离，可是到最后一小段时，穿线器就卡住了，怎么使劲也捅不动。墙内的管道不是平滑过渡的，有的地方可能有90度的直角。无奈又把钢线拉出来，从另一个口往里捅。结果还是一样，到最后一段的时候怎么也捅不动。当我再次把穿线器拉出来时，发现拉都拉不出来了。后来穿线器拉出来了，可反复试了几次都没穿成功。</p>
<p>最后，经过全家人的努力，终于成功了。我们在穿线器头部帮上一段毛线，捅到头后，再用一根细铁丝在那头勾，勾到毛线把毛线拽出来，再拉着穿线器的头，终于穿出来了。</p>

<h3 id="管道不通"><a href="#管道不通" class="headerlink" title="管道不通"></a>管道不通</h3><p>在穿客厅的线不成功时，我又想试试先穿到房间三的管道吧。结果一样的，不管从哪头往里穿，都是到一定程度就堵住了。期间也有过多次穿线器拔不出来的情况。而且听声音，好像位置不太对。装修时候的管道图早就弄丢了，现在谁也不确定这两个房间的管道是不是通着的。无奈放弃了这个房间的穿线工作。</p>
<h3 id="网口面板线路不通"><a href="#网口面板线路不通" class="headerlink" title="网口面板线路不通"></a>网口面板线路不通</h3><p>面板就是下面这个东西，感觉就是起到了个美观的作用。接线的时候可是费了老劲了，因为墙里的网线长度刚刚好，实在不算富余，所以接线时候姿势就很难拿。好不容易把8根线屡直了，按照颜色放入对应凹槽内，压好，用测线仪一测，5、6两根芯不通。反复试了几次，还是不行，无奈放弃了面板。</p>

<h3 id="网线钳质量差，水晶头接触不良"><a href="#网线钳质量差，水晶头接触不良" class="headerlink" title="网线钳质量差，水晶头接触不良"></a>网线钳质量差，水晶头接触不良</h3><p>网上不到30块钱买的网线钳套装，压了十来个水晶头就出现了质量问题，压不到位，8芯只通一两芯。回到商品评论区一看，果然有前辈有相同的遭遇。</p>
<p>这网线钳压完了，水晶头的8个金属片没有刺破线缆外皮，接触不到里面的金属线，导致线路不通。无奈跟店家反映问题，店家还不错，答应再发一把新的过来。</p>

<li>折腾了半个多月，虽然遇到了困难，总算把网络改造好了。家里的大多数设备都实现了高速上网，进一步压榨了网络运营商。</li>
<li>对于自己来说，提高了动手能力，增加了一些经验，丰富了人生阅历。同时自己长了个教训：别以为什么东西都像想象中那么简单，行动之前先和有经验的人交流一下，也许会事半功倍。</li>
